About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X475-40S
The AirTAC SAIJ200X475-40-S is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty applications. Equipped with a rear mechanical adjuster, this model provides a usable travel window of 435-475 mm, allowing you to dial in the exact retract position without swapping hardware. The integrated magnet (-S) supports position sensing via AirTAC CMSE reed and DMSE electronic switches.
This bore size utilizes a robust 40 mm carbon steel rod with an M36x2 thread, paired with a G3/4 PT tapered port to handle massive air volumes. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting. While the adjustable stopper and variable air cushions manage end-of-stroke deceleration effectively, neither component will hold a load without live air pressure; for true load-holding, consider the SAIL or BSAI series.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X475-40S Is Used
Heavy Press Tuning
Fine-tune the 435-475 mm retract distance on heavy stamping or pressing lines to accommodate varying material thicknesses without recalibrating external hard stops.
Large Assembly Changeover
Adapt automated heavy machinery to new product dimensions by simply turning the rear adjuster, avoiding the downtime of physically replacing a 200 mm bore cylinder.
Position Calibration
Use the 40 mm adjustment window to precisely calibrate the end-of-stroke position during machine commissioning, ensuring perfect alignment of heavy industrial components.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X475-40S the Right Cylinder?
Selecting the SAIJ200X475-40-S is ideal when a machine requires extreme thrust—up to 3204 kgf at 1.0 MPa—combined with on-the-fly end-position tuning. Conversely, this 200 mm option is chosen when pushing or lifting heavy assemblies where a fixed-stroke SAI cylinder would risk mechanical binding during product changeovers. To replace an existing ISO 15552 cylinder, match the 200 mm bore, 475 mm stroke, 40 mm adjustment range, G3/4 port, and the -S magnet requirement.
Because this cylinder features a 475 mm stroke, the extended 40 mm rod is subject to significant side-loading if the load is not perfectly guided. You must use an external guide rail to prevent rod bending and premature seal wear. Furthermore, the rear adjuster acts purely as a travel stop for the 435-475 mm window and does not function as a mechanical lock; air pressure must be maintained to hold the load in place.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ200 Adjustable Cylinder SAIJ200X475-40S FAQ
At its maximum rated pressure of 1.0 MPa, it can deliver up to 3204 kgf of push force.
The rear adjuster allows you to shorten the effective stroke by up to 40 mm, creating a usable travel window of 435-475 mm. This stopper fine-tunes the end position at commissioning but does not lock the load without continuous air pressure.
